Thunderbird Support Forum

Using TB version 102.10.1. Been recently getting messages from three different senders that I wish to delete before they hit my inbox. I read the help article at https://support.mozilla.org/en-US/kb/blocking-sender and followed the directions to set up a Block List filter, adding the senders to it. It seems to work automatically for two of the senders but not the other...I have to manually run the filter to make it work. Seems kinda pointless when, if it hits my inbox, I can just delete it anyway. Any ideas why it is still getting through the filter and how to fix it? See screenshots attached.

I would like create a back up of my local folders (26 years of emails) in the cloud. Reading questions posted here, the recommendation is to backup the complete 'Profiles' folder. However, when I try and do so, I am not successful because at some point the backup process glitches out. (I am trying to upload the folder to a Microsoft OneDrive folder and have tried on both my PC running Windows 7 Pro and a Macbook running OS Monterey.) I suspect that my internet connection is not stable enough to copy 30 GB (about the size of the 'Profiles' folder). Is there any alternative to backing up the complete 'Profiles' folder?

Most of my work life is in email. Over 25 years (starting with Mulberry) I have built up a custom IMAP folder hierarchy that makes work manageable, but Thunderbird 115 has broken this, now displaying nested subfolders at the top level sorted alphabetically. See the images for before and after. For example, there are now three "Administrative" folders that were formerly classified under superordinate folders for my roles as lab leader, graduate program chair, and departmental faculty member. Persons who used to be in Colleagues or Students subfolders are now at top level. Inexplicably, a few folders retained their hierarchy but most are flattened out. Now I need to scroll through hundreds of folders (have not counted recently but in the late 2000's I had over 500.)

I was able to revert to 102.14 using backups, but will be stuck with this version for the rest of my career unless Thunderbird fixes these problems. Thunderbird is so important to me that I make an automated monthly donation to the project, but will have to cancel if this is not fixed.

If anyone has found a work around please LMK. And Thunderbird team, please acknowledge and LMK whether this will be addressed or are IMAP users left behind?

Thanks, Dan Suthers

I am getting the Mozilla Thunderbird Email wants to access your Google Account all the time while using TBM, I have removed the gmail account and the pop up does not show, so I know it is for the email account just removed. I re-add the email address and enter the email address and password and let it find the config itself. Click Done, and get the Mozilla Thunderbird Email wants to access your Google Account again, then click Allow and get the Authentication failure while connecting to server imap.gmail.com. message in the bottom left of my desktop. How can i get gmail to work again please.

TB 91.7.0 (64-bit I used to send/rcv gmail no problm, started having issues ~ Oct 2021 I then setup a 3rd party app password in gmail account for thunderbird. That allowed me to Send Gmails, but, not receive it kept asking for password. Then I read to use OAuth2 and saw that Google will no longer allow 3rd party app passwords, so i deleted it in google, and set both Imap.gmail.com and smpt.gmail.com to use OAuth2 (both set for SSL/TSL). I did this just for smpt first when the 3rd party app password was still enabled, i could recv but, when i went to send, it would ask for password, i enter it, then it would sent msg to my cell phone to Allow thunderbird, i would press Allow on my phone, and Thunderbird would come up with Sending message.. with the progress marked all way to end BUT, it will never complete sending.... I have to hit cancel it then shows Failed message unable to authenticate. After I deleted the 3rd party app password in gmail settings, now when i start thunderbird or try to receive emails, it goes through the same authorization process with my phone, but, then never downloads any new emails. I have spend HOURS on this.. extremely frustrated (I have been forced to us ms mail which i really don't like, i am too used to thunderbird (although I wished thunderbird had check boxes on emails to select via checkboxes for delete, or moving, etc)

Lately I'm having trouble with my connection with outlook. I use a free outlook email address. Sometimes (not always) when starting Thunderbird, I get the "user authenticated but not connected" warning. After a while it's working again.

I have tried several settings but can't figure out what solves this issue.

I'm using port 993 / SSL/TLS and authentication method is set to normal password.

Most of the times this works.

When I switch to OAuth2, I get the Microsoft screen to login to my work / school account which I do not have.

I've search the web to find a solution for this but I can't find it. Hopefully someone can help me out because it drives me "nuts" ;)

I have used Thunderbird for more than 15 years and have always liked the way it works and promote it to anyone needing an email client, but the latest version 115 Super Nova is terrible. I don't like the font or anything in the update. Now I just found a new problem. Since last update messages show all previous messages from same sender with current message at the bottom of list. I have looked for a way to change this but have not found anything. It used to work so good and now it sucks.

Tb 102.14.0 (64-bit)

I followed the instructions to copy the msgFilterRules.dat file to the D:\drive, then copied it to the IMAP profile. When I then opened Tb, which starts with the IMAP account, I found that there was only a single filter copied from the filter collection in the POP account.

What do I need to do to get the POP filters properly transferred to the POP account?

Hi, I have a problem with attaching vCard to the single message. I can attach it to all messages in acount settings (see mail-2) but "Personal Card" option is inactive (see: mail-1).

I've no idea what's the problem

Hello Thunderbird Community!

I have an issue that MANY people encounter nowadays, meaning having an old or current e-mail inbox online reaching it's maximal capacity...

I would like therefore to be able to:

1. Be able to download everything on my PC/Laptop - No problem with that, already done by the way

2. And then being able to delete 80% of the e-mails on the server - but NOT on my PC - and doing so directly VIA Thunderbid by selecting/filtering in one single operation these 80% of e-mails by stating for example: all e-mails received since the beginning until 6 months ago to be deleted but only on the online server NOT in my PC

In the end I will then have: - All my e-mails since the beginning still safely and forever on my PC - 80% of the received e-mails until 6 months ago removed from the online server and online inbox platform so as to get back again plenty of space

Two questions: 1. Is this possible? 2. How?

Thank you very much guys!

I am very unhappy with this new Thunderbird update to 115.3.1. Everything being changed is killing my office's productivity. How can I roll back that update to the one before it.

Alternatively, is there any way to make this new update look and act like the previous version. I want all the control buttons back that used to be there.

I'm having an issue that's related to 115 as I didn't have this problem on 102. This is also not related to gmail, live.com, icloud or other exchange accounts, only my IMAP accounts are having this problem. I have it set to a unified folder and I display both sent and inbox in the thread. Some of the items in the inbox show twice and some, if not most of the items in the sent folder on the thread show twice as well.

About 10 days I started getting nthe following error message.

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Too many failed authentication attempts.

I have a gmail account and this works fine, my incomming POP account is OK, but the outgoing mail mostly will not send. The error corrects itself occasionally and works OK. I have checked all the settings and raised 2 calls to LCN who assured me the error was not at their side (my webmail still works OK). Any suggestions, I have deleted the password and re-entered it. Many thanks .

I have installed Thunderbird and logged in via Google account and I have no problems with receiving e-mails, unfortunately sending out does not work. Somebody told me to choose OAuth2 but this option does not exist for the "sending out" server. My email is on gmail. What to do? Witoldrem

I had problems with thunderbird email text too small. Resolved that but now the title line with subject to and from is too large. How do I change it. Windows 11 latest version of thunderbird.

I use Thunderbird email on my Windows 11 computer. My ISP for this is AOL. As of yesterday, 27 Aug 2022, I can not receive email and get this error message "The server does not support the selected authentication method. Please change the "authentication method" in the "Account Settings/Server Settings". My server settings are set to the AOL requirement of OAuth2 and have been working fine until yesterday. My Thunderbird was upgraded to 102.2.0 about the time that I noticed the email problem. Only the incoming server is affected; I can still send outgoing mail. I have the same problem on a second computer that is running Windows 10. Thunderbird on that computer was also upgraded to 102.2.0. How can I fix this issue?

Update 29 Aug 2022 - The above quoted error message from the server goes away if I change the Authentication method for the incoming server to "Normal Password" instead of "OAuth2". When I provide my AOL password (which is valid because I am able to log directly into AOL email) I get this message "Sending of password for user vvchamb did not succeed. Mail server pop.aol.com responded: [SYS/TEMP] Server error - Please try again later." About a year ago AOL required me to change the authentication from Normal Password to OAuth2 and this has worked until the latest Thunderbird upgrade.

Thunderbird can no longer receive gmail> I go round and round in a loop. Sign in with your google account. Notification sent to my phone. Yes it's me. select a number. Mozilla Thunderbird wants to access your Google Account - Allow Secure Connection Failed.

Still waiting for help with my annoying thunderbird problem. Once you help me solve it, my donations will begin. The browser link in my incoming email stopped working about 3 months ago. I have to right click on the link, start my browser manually and paste the link. I've tried it with Firefox, Edge and Chrome (preferred) and none of them work.

Two days ago Thunderbird no longer would send emails (been using it without problems for 7 years) I have read all the previous posts on this. Tried sending emails after disabling firewall and Malwarebytes without success. I can receive emails sent from my Spectrum email account (still works). I can send emails from my iPhone using the identical Outgoing Server Settings. The settings are in the screenshot. Also downloaded the latest version of Thunderbird today. Didn't fix it. To get around the problem right now is I am composing my emails (IMAP), saving them in my drafts and then sending them from my iPhone.Any ideas? Thank you!
